I hear positive results from Livernois motorsports regarding there 93V3 TUNE,pretty sure they were the first ones to tune the XSPORT,with an added 3-bar map you will see even greater results,good luck.
Welcome xsport, glad to have you and your '14 X here! The tuner debate is a personal choice, depends on the specific features you are looking for. If you want to upload & go, either tuner will be fine. If you want to datalog & refine your tune remotely, Unleashed is the best choice ATM. If you want to dyno tune your vehicle, either tuner can do it.
If you like the thought of datalogging, a good way to get your mind around it is to run a Bluetooth (or WiFi) OBD II adapter & Torque Pro (Android only) software. Obviously not going to be as precise or have as many available parameters as a tuning device, but gets your head in the game
BTW, post up some pics of your ride! When did you acquire it?
Thanks Shodded! my sport is due for a wax and wash so I'll post pics as soon as I get it done! I'm pretty much a newbie when it comes to these things. I'm basically looking for the maximum power output and best MPG I can get from a tune. Also would like something safe given the extended warranty we got.
